Swap Agent

The Swap Agent is a specialized token swapping agent that leverages the 0x protocol to provide optimal token swaps with competitive pricing, minimal slippage, and efficient execution across multiple DEXs and AMMs.

Overview

The Swap Agent serves as the primary token swapping engine for the Ava Portfolio Manager system, integrating with 0x protocol's aggregated liquidity to provide users with the best possible execution for their token swaps. It handles everything from price discovery to transaction execution while maintaining high standards of security and efficiency.

Key Features

  • 0x Protocol Integration: Leverages 0x's aggregated liquidity from multiple DEXs

  • Optimal Price Discovery: Finds the best prices across multiple liquidity sources

  • Minimal Slippage: Advanced slippage protection mechanisms

  • Multi-Chain Support: Supports swaps across multiple blockchain networks

  • Smart Order Routing: Intelligent routing for optimal execution

  • MEV Protection: Built-in protection against MEV extraction

  • Real-Time Price Updates: Live price feeds and market data

  • Advanced Order Types: Support for limit orders and advanced order types

Core Components

0x Protocol Integration

Advanced integration with 0x protocol for optimal swap execution:

interface ZeroXIntegration {
  // Get swap quote from 0x API
  getSwapQuote: async (params: SwapParams) => {
    const quoteUrl = `https://api.0x.org/swap/v1/quote?${new URLSearchParams({
      sellToken: params.fromToken,
      buyToken: params.toToken,
      sellAmount: params.amount,
      takerAddress: params.walletAddress,
      slippagePercentage: params.slippage.toString(),
      excludedSources: params.excludedSources?.join(','),
      includedSources: params.includedSources?.join(','),
      skipValidation: 'false',
      intentOnFilling: 'true',
      feeRecipient: params.feeRecipient,
      buyTokenPercentageFee: params.fee?.toString()
    })}`;
    
    const response = await fetch(quoteUrl, {
      headers: {
        '0x-api-key': process.env.ZERO_X_API_KEY,
        'Content-Type': 'application/json'
      }
    });
    
    if (!response.ok) {
      throw new Error(`0x API error: ${response.statusText}`);
    }
    
    const quote = await response.json();
    return quote;
  };
  
  // Execute swap transaction
  executeSwap: async (quote: SwapQuote, options: ExecutionOptions) => {
    // Validate quote is still valid
    const validationResult = await this.validateQuote(quote);
    if (!validationResult.isValid) {
      throw new Error(`Quote validation failed: ${validationResult.reason}`);
    }
    
    // Prepare transaction
    const transaction = {
      to: quote.to,
      data: quote.data,
      value: quote.value,
      gasLimit: quote.gas,
      gasPrice: quote.gasPrice
    };
    
    // Execute with safety checks
    return await this.executeWithSafetyChecks(transaction, options);
  };
}

Smart Order Routing

Intelligent routing system for optimal execution:

interface SmartRouting {
  // Route optimization algorithm
  optimizeRoute: async (swapParams: SwapParams) => {
    // Get quotes from multiple sources
    const sources = await this.getAvailableSources(
      swapParams.fromToken,
      swapParams.toToken
    );
    
    const quotes = await Promise.all(
      sources.map(source => this.getQuoteFromSource(source, swapParams))
    );
    
    // Analyze and rank quotes
    const rankedQuotes = this.rankQuotes(quotes, {
      priceWeight: 0.4,
      slippageWeight: 0.3,
      gasWeight: 0.2,
      reliabilityWeight: 0.1
    });
    
    // Select optimal route
    const optimalRoute = this.selectOptimalRoute(rankedQuotes);
    
    return {
      route: optimalRoute,
      expectedOutput: optimalRoute.buyAmount,
      priceImpact: optimalRoute.priceImpact,
      gasEstimate: optimalRoute.gas,
      sources: optimalRoute.sources,
      confidence: this.calculateConfidence(optimalRoute)
    };
  };
  
  // Dynamic routing based on market conditions
  adaptiveRouting: async (swapParams: SwapParams) => {
    const marketConditions = await this.assessMarketConditions(
      swapParams.fromToken,
      swapParams.toToken
    );
    
    // Adjust routing strategy based on conditions
    if (marketConditions.volatility > 0.05) {
      // High volatility - prioritize speed and certainty
      swapParams.slippage = Math.max(swapParams.slippage, 0.02);
      swapParams.excludedSources = [...swapParams.excludedSources, 'slow_sources'];
    }
    
    if (marketConditions.liquidity < 0.5) {
      // Low liquidity - split orders
      return await this.splitOrderExecution(swapParams);
    }
    
    return await this.optimizeRoute(swapParams);
  };
}

Slippage Protection

    // Adjust based on market volatility
    const volatility = await this.getTokenVolatility(params.fromToken, params.toToken);
    const volatilityAdjustment = Math.min(volatility * 0.5, 0.02); // Max 2% adjustment
    
    // Adjust based on order size
    const orderSizeImpact = await this.calculateOrderSizeImpact(params);
    
    // Adjust based on liquidity
    const liquidityAdjustment = await this.calculateLiquidityAdjustment(params);
    
    optimalSlippage = Math.min(
      optimalSlippage + volatilityAdjustment + orderSizeImpact + liquidityAdjustment,
      0.05 // Max 5% slippage
    );
    
    return {
      slippage: optimalSlippage,
      breakdown: {
        base: params.userSlippage,
        volatility: volatilityAdjustment,
        orderSize: orderSizeImpact,
        liquidity: liquidityAdjustment
      }
    };
  };
  
  // Real-time slippage monitoring
  monitorSlippage: (transaction: SwapTransaction) => {
    const monitor = setInterval(async () => {
      const currentPrice = await this.getCurrentPrice(
        transaction.fromToken,
        transaction.toToken
      );
      
      const priceChange = Math.abs(
        (currentPrice - transaction.quotePrice) / transaction.quotePrice
      );
      
      // Alert if price moves beyond threshold
      if (priceChange > transaction.slippageTolerance * 0.8) {
        this.eventBus.emit('slippage-warning', {
          transactionId: transaction.id,
          priceChange,
          currentPrice,
          quotePrice: transaction.quotePrice
        });
      }
      
      // Cancel if price moves too much
      if (priceChange > transaction.slippageTolerance) {
        this.cancelTransaction(transaction.id);
        this.eventBus.emit('slippage-exceeded', {
          transactionId: transaction.id,
          priceChange
        });
      }
    }, 1000); // Check every second
    
    // Store monitor for cleanup
    this.activeMonitors.set(transaction.id, monitor);

    const patternCheck = await this.checkSuspiciousPatterns(transaction);
    
    // Volume monitoring
    const volumeCheck = await this.checkVolumeThresholds(transaction);
    
    return {
      sanctionsCheck,
      patternCheck,
      volumeCheck,
      approved: sanctionsCheck.clean && patternCheck.clean && volumeCheck.clean
    };
  };
  
  // Reporting and alerts
  generateComplianceReport: async (timeframe: string) => {
    const report = {
      totalSwaps: await this.getTotalSwaps(timeframe),
      totalVolume: await this.getTotalVolume(timeframe),
      flaggedTransactions: await this.getFlaggedTransactions(timeframe),
      riskDistribution: await this.getRiskDistribution(timeframe),
      complianceScore: await this.calculateComplianceScore(timeframe)
